The object of this invention is to providean engine either an internalcombustion engine or a steam engine or a pump which. has but I haustpipe is shown on the outer side of the cylinder and an exhaust port 21of each cylinder communicates from theinside of the cylinder to thisexhaust pipe.

The object-of this invention is, further, to

10 provide a piston'in a cylinder which when it 20 ast the inletmanifold to heat the incoming el. Thisexhaust passage and intakemanifold are preferably located within the holing' drawingsin whichFigure 1 is a section throu h the cylinders of an engine of my improvetype and also showing the main shaft n section. Figure 2 is an end viewof an en- 80 gine such as shown in Figure 1 and consisting of fourunits, the upper one beingshown in full lines and partly broken away toshow the interior construction. I

The cylinders are shown at 10 and 11 and are opposed and axiallyaligned. Each cyl-' inder contains a piston 12 and these pistons areconnected by a shaft 13/which may have a central support such as thebearing 14 in which the shaft both 'rotates and slides...

Abutments 15 are placed where the rear cam 'faces 16 of the pistons bearon them t9 cause the rotation of the piston when the "piston isreciprocated toward the abutment. In the form shown these abutme'nts areprovided by I 14. The main shaft is shown at 17 and is rotated byagear17' in mesh with a pinion 18 on the shaft 13, the shaft 13 being'arra'n ed so that it can rotate the pinion 18 but slide therein, and Ishow I a feather 19 for such function. A main exits power stroke theother piston is operating on its compression stroke or its scavengingstroke. The ports 21 are opened by reason of the piston movingfar-enough to uncover the I port 21'. A k

The engine I illustrate is an internal coinbustion engine and I/ showspark plugs 22 to indicate the power end of the pistons.

At the inner side of each piston is ,a port 23' and within the shaft isan exhaust passage 24 and aninlet manifold 25, the latter carrying thefuel mixture. This exhaust passage and the intake manifold rotate withthe shaft so that the exhaust'opening 26 of the exhaust passage 24 andthe inlet passage 27 of the intake manifold functionally register withthe -port 23 in a cylinder.

In the case of four units,-each consisting of two cylinders as shown inFigure 2, they main shaft 16 is" rotated at halfthe speed of therotation of'the shaft 13 and this operates r j these cylinders in theirproper sequence so that theymay successively operate to rotate the mainshaft. As these cylinders can be arranged to have their operationoverlapping and in the absence of unbalanced valves and crank shafts,vibration is eliminated.

A manually operated control member 1s interposed between the passages inthe shaft i and the port 23 of the cylinder. This is illustrated as asleeve 28 which has a flange 29 regulated by a pinion 30 which the teeth31- on the flange.

The pinion 30is on a shaft ates a similar pinion on the other end oftheengine. The sleeve 28 has the, port or passage 33, one for eachcyl1nder, and as the sleeve is advanced or retreated the duratlon of theexhaust and, more particularly, the 95 point of cut-off of the fuel canbe controlled. In this engine the exhaust at first is through the majoropening 21 and when this is closed by the return of the pistonlthe'gases are forced out through the ports 23, 26 and 33 m9 ,7

meshes with A 32 which operand thus through the exhaust passage 24. Thisinsures a complete scavenging and also heats the intake manifold 25 andthus heats the incoming fuel. As the shaft turns it x presents theintake manifold, the port 27 comes around to port 23, the piston is onits suction stroke and the cylinder is changed.

' The sleeve 28 by its adjpstment varies the reciprocation.
